. Referring first tofthe general construction of the yehicle-fr'ame, as'illustrated in Figs. 1, 2, and 3, A indicates the vehicle-body,which is supported upon the running-gear and is preferably so shaped as to cover or -in'close the motor and all of the working parts of the vehicle, said body being provided at its front end with a seat A. for the operator.'- The I running-gear consists generally of a front axle B, provided with wheels 0 C, a rear axle 1), provided with wheels E it, two pairs of external longitudinal frame pieces F F, a air of central longitudinal framefmembers F F,

and two rear transverse frame members F'F located somewhat'to the rear of the. rear axle, the frame members constituting each pair being located one above another, so that the upper one of the pair only appears in the plan view, Fig. 3.

The frontaxle 15 consists of upper and-lower" parts 12 b, which converge. and meet-attire gator ends of the axle to form the axle ends axle to swing on a central horizontal pivot,

Said front axle is connected with the front; ends of the main frame by a swivel-joint or pivotal connection adapted to permit the front cernedand provision ,.being made for the steering of the vehicle throiigh the medium of the pivotal connection of the frontwheeI- bearing's with the ends of the-axle,.as will hereinafter appear. .The pivotal connection of the front axle with'the frame isshown as formed by means of ahorizontal lon 'tudiiOO plate or dislrF, the central frame parts 'F'being attached at their front ends to-the up r andilower parts of the disk, while the slde frame-bars am bent inwardly at their front ends and-secured at opposite sides of the central parts. The pivot-shaftG is secured to the center of said disk, 'conwgeniently by being inserted through the-central aperture in'the' disk and secured therein-by a nut g, Fig. 4 At its forward end the sleeve G is provided with upwardly and downwardly projecting parts 9 for the attachment of the upper and lower portions-bot the front axle. At its rear end the said sleeve is provided at its inner end with an annular integral bearing ring or flange g, which rests against the front face of the disk F and aids in maintaining the said sleeve at all times'in perpendicular relation to the-disk, said flange thereby taking part of the lateral strain from the bearingshaft G. The front axle is further shown as provided with rear oblique braces B B, which extend from the outer ends thereof rearwzirdly-and inwardly and areattache'd to the rear end of the sleeve G',-as' clearly seen in Fig. 3. The said pivot-shaft G carries at its front end a vertical bearing-sleeve G, which affords support for thelower end of a vertically-arranged rock-shaft H, through the medium of which the vehicle is steered, said shaft having at its upper end ahand-lever.

II, Fig. 1, by means of which the rock-shaft may be actuated by the operator.

'Now referring to the pivotal connection of the front wheels with the front axle, by'which the-steering is accomplished, this feature of the invention is illustrated in Figs. 2, 3, 18, 19, and 20 andjs constructed as follows; In said figures, Vindicates the extremity of the front axle, which latter, as before stated, is

incapable of any horizontalmovement with I respect to themain frame. The axle ends b extend to points centrally .within the wheelhubs C and arethere connected by vertical ivots c with axle sections C, on which the hubs are mounted and which correspond in function with the axle of an ordinary carriage. Said axle-section C'is provided with a recess 0' toreceive the end b of theaxle, which recess is made of sndicient horizontal width to. admit of a considerable range of oscillatory movement of the axle-section with relation to thejaxle, the recess being conveniently made with outwardly-flaringsidewalls, as seen in Iii 20. Toprovide room forsuch recess, the

a e-section C is made ofconsiderable diamstar at its inner end, while the hub C isenlargedto correspond therewith. In the particular construction herein shown the inner part of the axle-section C is providedwith an annular portion 0, Fig. 19, upon which is placed a bearing-ring c, forming a part of a ball bearing, the outer part of which bearing con--- sists of a ring 0', which is fitted within a suitable annular recess in the hub O. The outer end of'the axle-section, exterior to the recess" 0', is preferably made in the form of a spindle c, on which is mounted A ring a, mining the inner member of a ball-bearing, the-outer member of said ball-bearin g being .for'med by a ring 0', inserted in an annular recessjat theouter end of the hub.

Arigid connection of the axle end. with the axle-section C is of course afforded by too pivot-pin c; but-in drderto take a part of the strain, from said pivot-pin and to more certainly hold the axle-section rigidly in place with respect to theaxle, while allowing said axle-section to swing horizontally-on said 8 pivotin, the top and bottom walls of th'e'recans are made horizontal and parallel with each other and adapted-to fit closely against the top-and bottom surfaces of the axle, and which latter is provided with flat top and bottom bearing-surfaces for engagement with the upper and lower walls of the recess. In the particular construction illustrated such hori-.

the same vertical plane with the wheel-rim.

The wheel as a whole is therefore pivotally connected with the axle, so, as to swing on a vertical axis passing through its point of contact with theground or supporting-surface, This construction is of very great advantage in the practical use of the motor, for the reason loo that the wheel when thus mounted has no tend- 'ency upon striking an obstacle to swing or oscillate in onedirection or the'other, and this is truewhether the obstacle be a high or a low one, or, in other words, whether the resistance to the forward movement of the ,wheel acts upon the wheel at a point near the ground or at a'point horizontally opposite the axle.

By the, construction described, therefore, the

difiiculty of steering the vehicle is very greatly reduced, it being obvious that whether the wheels be. inclined to. theright or left in turning or are held straight for moving in-a straight line the striking of an obstacle bythe wheel will have no tendency to swing the wheel ineither direction, and thus contaet'of a wheel with such obstacle will not, therefore,

cause the vehicle to departfrom its correct course. I

Now referring to the meansfor actuating or moving t wheels from the steering rockshaft H, each of the axle-sections C'is vided on its inner end with a rigid forwa projecting arm 0, Figs.3, 18,and 19, and to the forward ends of said arms are pivotally joined connecting-rods II, the opposite or innet ends 'of which are pivoted to forwardlyprojeeting arms h' h on the said rock-shaft H. In the particular construction illustrated the said arms h are attached to a sleeve 7b, which is attached to the lower end of the rock-shaft'II and surrounds the same within the supporting-sleeve G", said sleeve being provided between its upper and lower ends with a horizontal slot g through which the arms project, and having a vertical slotg", through which the arms are carried in inserting the sleeve h into the sleeve G The rearor driving axle D is mounted in bearings f f, which are attached, by means of inclined braces f f, to the upper and lower external longitudinal frame-bars F F.

The motorillustrated in connection with the machine described is an explosive-gas engine provided with two oppositely-disposed -horizontally-arranged power-cylinders I I and a crank-shaft I, on which is mounted a balance-wheel I. Said engine is mounted on the upper longitudinal frame-pieces F F, at one side of the machine-frame, with the cylinders arranged longitudinally of the frame and the crank-shaft transversely thereto or parallel with the rear axle. The engine is shown as supported on the frame-pieces by means of cross-girths i i, Fig. 3.

Now referring to the gearing by which the .rear axle is driven from the said motor, these parts are constructed as follows: J is a crankv14,-oscillatory clutch-arms L L, carrying clutch-dogs M M, which 'eugage'the margin of said disk, and two connecting-rods N N, Fig. 1, which serve. to connect the wrist-pin T J with the vibratory clutch-carrying arms L L, said'clutch-carrying arms being disposed at opposite sides of the clutch-disk, so that when both clntch-leile jiam oscillated through the medium of the connectingwods M one clutch-dogwill makeits power or propellin g strokeat thetime the other one is making its rear-ward or return stroke, and both of them together will maintain the clutch-disk constantly in rotation. The clutch-disk K is shown as mounted directly upon the rear axle, and in Figs. 1, 2, 6, 7, 8, and 9 devices are shown for moving the wrist-pin J inwardly and outwardly across the face-of the disk K for the purpose of varying the speed of the vehicle. In Figs. 10, 11, and 12, however,

is shown a modification of the driving-gear wherein the speed-regulating devices instead of being located in the crank-disk are mounted on as separate oscillatory part actuated "from fiiefsaid crank-disk.

Referring now-to the clutch-disk and the operative parts by which the same is turned, these features are illustrated in Figs. 13 to 17 and are made as follows: The clutch-disk K is provided at its outer edge with a lateral cylindric flange k. Mounted concentrically with the axle D at the'sideof the disk at which-said flange projects are the two-oppositely-extending clutch-arms L L, said arms in this instance being mounted directly upon said axle. Said clutch-arms are shown as provided with overlapping parts, which are apertured for the passage of the axle D, these parts in the case of the upper clutch-arm L having the form of-two annular parts or hubs L313, which extend at opposite sides of the central annular part or hub L of the lowermost clutch-arm L. The clutch-dogs M M are pivoted to the inner faces of the arms L L by means of pivot-pins m m, located between the shaft and the periphery of the clutchdisk, and said clutch-dogs are provided at their outer ends with notches 911 471.", adapted to receive the flange k of the clutch-disk, said notches being so shaped and proportioned that when the clutch-dog stands in a radial position it may move freely along thefiange, but when the dog is inclined in either, direction the opposite sides of the notch will'frictionally engage the said flange. The direction in which the dogs are inclined determines the direction of motion of the disk, so that by shifting said dogs from. one side to the other of their central or radial position the direction of motion of the disk may be reversed at will. In order togive suitable freedom of' movement to the clutch dogs, necessary for the clutch action de= scribed,the openings through whichthe pivot= -pins m pass are enlarged or elongated longhtudinally of the clutch-dog, as clearly seen in Fig.15, this construction also enabling the dog to be shifted from one side to the other of its central position, its-is necessary in re'' versing the direction of motion of the vehi= cle. Mounted on the clutch-arms L L areoscillatorydog-shifting levers O O, the same,

being pivoted at their inner ends on pivot" pins 0 0, located near the inner ends of the clutch-arms and extending outwardly to points opposite the outer or free ends of the clutch-dogs, which latter are connected with said levers by means of spring-arms o 0 which spring-arms are attached to the outer ends of the lovers 0 O, pass through circu mferentially-elongated concentric slotsl Z in the clutch-arms L L, and are engaged with the clutch-dogs by means of notches or recesses in the rear or outer faces of the. latter.

The dog-shifting lovers 0 0 are for the purpose of shifting the dogsfrom one side to the other-of their central positiomas required to change the direction of motion of the clutchdisk, it'beiug obvious that when the dog-is swung at one sideof its central position'it will bite thcflange when moved in" one direction and when shiftedto the opposite side of its'central position it will bite theflange'when s have the effect t swinging the clutch-dogs "herein as formed their outer ends with the groove movin in the other or opposite direction. Such s ifting of the dogs is accomplished by throwing the free or-outer ends of the shiftins-levers O O laterally, and devices are provi ed for giving such motion to the said 1evers, as follows: Mounted on the axle-D is an endwise-sliding sleeve P,. provided with two annulargroovespp'. The groove. p is located at the end of the sleeve nearest the clutcharms LL, and in said hub L of the upper cIn'Ech-armare formed longitudinal guidegrooves 2'1;- while in the hub L of the lower clutch-arm are formed two similar guidegrooves Z Z. In one pair of diametrically opposite grooves Z Z are located slidingwedges Q Q, which are thicker at theirinnerthan'at their outer ends and which are engaged at of the sleeve 1 by means of lugs q q. .In t e other pairof. oppositely-arranged guide-grooves-l 1 are located other sliding wedges Q'Q', the same being thicker at their outer than. at ,their inner parts and being also engagediwith- The" the guoovejp by means of lugs q' dog-shifting lever A is providedne its'inner o'r pivoted end with two-oppositely-pm.

jectin arms 0 0*, each adapted to engage at its en withthe outer surfaces of the dissimilar wedges Q Q, which are mounted "in the said lever L. The end portions of said arms 0 0, which enga e said wedges, are shown y means of threaded bolts 0 0', which are inserted through the said arms -and are provided with jam-nuts, this construction affording means'for accurately adjusting the contact-surfaces'of the said arms with. respect to the said wedges. The lower. dog-shifting leverO is similarly provided with arms 0 0 for en agement with the Q, said arms be-' lowermost pair. of wedges ing-similarly provided with bolts 0" 0', which form adj nstable contactsurtaces-for engagement' with the said wedges. The pairs Q Q of sliding wedgeswhen moved longitudinally obviously serve to swin%or rock the shiftinglevers'on their pivots, it eing clear thatwh'en saidwedges are moved together in the same direction one will throw outward the shiftinglever arm opposed to it, while the oppositely- ;inclined wedge will permit the inwardmotion of the otherarm on the same shifting-lever, and vice versa.

. For givin endwisemovement tothesleeve P anysnita le actuating device-may be em- Ployed, that herein shown consistingot a bent.

ever R, pivoted to a bracket 1' on the main frame, engaged-at-its rear end with the groove p of saidsleeveand connected at its forwardly and laterally extendin which extends forwa to and is connected end witha rod with a hand-lever R, adjacent to the drivers seat. The shifting-levers O 0', when moved by the action of the sliding sleeve P, the sliding wedges, and other parts described, obviously from one side tothe other of their central-position and of thereby reversing the direction of rotation of the driving-wheels, such rotation being produced by the actionof said dogs on the clutch-disk when the clutch levers L L -areoscillated through the action of the crank-pin and the connecting-rods N N, as hereinbefore stated. The spring-arms o o obviously afiord the necessary yielding connection between the shifting-levers O 0 and upon the disk through power applied by the :operatorto the parts. Inasmuch as said disk I is in constant rotation. it is necessary to provide means for transmitting power for moving or shifting the crank-pin from stationary actuating parts upon the vehicle-body to the said revolving'disk, and the present invention involves the feature of a frictional retarding deviceor brake applied to annular moving parts upon the said disk in order to retard, said annular moving pars, and. thus turn the same with respect to the disk, such annular posts-being arranged to give motion to suitable gearing for shifting or moving the wrist-pin.

' Referring now to the means illustrated by which these results areaccomplished, the parts referred to are constructed in detail as follows: The wrist-pin J which, as before stated, slides in a T-groovej, formed in the face of the disk J, isengaged. with a screwshaft S, mounted in the inner part of said groove and has screw-threaded engagement with the inner part of the wristpln, which latter thereby constitutes a nut upon said shaft. For turning the screw-shaft S, and thereby giving motion to the wrist-pin, devices are provided as follows: In the rear or inner tune of the crank-disk J are mounted cylindric toothed or gear rings T andT', said rings being mounted to turn in the disk, and for this Purpose being'preferably mounted in annuar grooves formed ,in the body of the disk and confined therein by meansot rings 3 j j, which are secured to the rear face of. the disk by screws or otherwise and are arranged to overlap shoulders on the rings, so as to hold said'ri'ngs from outward motion. Said gear-rings are provided on their inner edges with gear-teeth, and the innermost ring intermeshes with a gear-pinion s on the shaft 8 while the outermost ringintermeshes with a gear-pinion ,9 whichis mounted one short counter-shaft S which counter-shaft is pro-,

vided with a gear-wheel s, that intermeshes side of the inner face of the crank-disk, so as to constitute, in elfect, two annular flanges thereon, and between the projecting portionsof said rings is located a brake -band U, which is adapted-to embrace and frictionally engage the innerringT'and is provided with external projections or shoes to u, adapted for frictional engagement with the inner surface of the outer ring T. The brake-band U is connected at one end with-a stationary pivot U, Fig. 6, and at its opposite end is attached to the lower end of a vertically arranged op vides a means for turning the screw-shaft S in either direction, and thereby moving the crank-pin inwardly and outwardly on the disk, it being obvious that if the brake-band Ube tightened againstthe gear-ring T said gear-ring will be held from turning with the crank-disk,and the screw shafts will be thereby rotated by the action of the said gear-ring on the pinion s, and it being also obvious that if the said brake-band be expanded to bring the shoes it into contact with the outer gearring T said gear-ring by being retardedwill turn the counter-shaft S and that the motion of the latter will be transmitted to the screw-shaft, so as to turn the same in a direction opposite to that in which it was turn ed by the action of the inner gear-ring. It follows from the above that by moving the handlever U out backward and forward the wristpin J may bemoved either inwardly or outwardly on the crank-disk, with the effect of increasing or decreasing the throw of the clutch-arms and correspondingly increasing or decreasing the rate of feed or rotation of the clutch-disk. It will be obvious, moreover, that if the crank-pin be shifted to thecenterof the disk no motion will be given to "the clutch members and the machine will'be.

stopped.

In Figs. 10 to 12 we have shown a construction wherein variation of speed is produced by devices generally like that before' described, but in which the speed-changing mechanism is located in a movable part which is separated from the crank-disk. In this instance the w'rist-pin J' is permanently clamped or secured in the groove j and is not intended to be moved, except for the purpose of adjustment. In this instance, moreover, the

- clutch-disk K, the clutch members, and the nio'ns a), by which it is mounted-in suitable bearings affordingthe necessary oscillatory movement in the upper part of the frame. The saidl'nam'e consists generally of two parallel. guide-bars, between which is located a sliding block V, to which the connecting-rods NN are pivot'ally attached. 1 Preferably the block V has two wrist-pins V at either side thereof, and the connecting-rod Nis forked at its ends to form two arms 11. n, which are engaged at their ends with the said wristpins.

- v In the ends of the frame V is mounted a longitudinal screw-shaft V to the lower end of which, below the frame, is attached a'bevel gear-wheel V, said bevel gear-wheel meshing with a second similar wheel V attached to a shaft 0', having hearings in one of the trunnions 'v of the-frame On' the outer end of said shaft 2) is secured a sprocket-wheel V,

and over s'aidwheel is trained a chain belt '0 which also engages a sprocket-wheel '0 on v a counter-shaft v An upright shaft V extends upwardly from the shaft vi-and is'con-' nected therewith by intermeshing gear-pimions 12 v ,,s aid shaft V having at its upper end a hand-wheel V", by which the shaft may be turned by the operator.

From the construction described itis obvious that through the medium of the shaft V and gearing described the screw-shaft V may be turned or rotated so as to carry the block V toward or away from the center of oscillation of the frame V, and inasmuch as the extent of movement given to the connecting-rods N and N.will depend upon the diSrx tance of the wrist-pin from the center of 0scillation of said frame it. follows that the speed of the machine may be readily controlled by the use of the device described.

Both of the connecting rods N and N may be pivotally engag'edwith the wrist-pin J or V but. as a more simple and preferable construction one of the connecting-rods,'as N, is directly engaged with said wris w'pin, while the otherconnecting-rod, as N','is pivoted to the first connecting-rod near the wrist-pin by a pivot connection n. f

Several of the featuresof construction illustrated and above described may be used with advantage by themselves or in'other combinations than that in which they are illustrated, and-we do not therefore desire to be limited'to any'of the combinations of parts or details herein shown and described, except so far as the same may be specified in the accompanying claims.
